Triaenodes tridonatus Ross

Three-tooth Triaenodes Caddisfly (Triaenodes tridonatus)

The Three-tooth Triaenodes Caddisfly was described in 1938; it is known from populations in Alabama, Florida and Oklahoma, USA.

The Florida and Oklahoma populations appear to have been last seen in the middle 1930s, while the population in Alabama survived at least until 1991, when it was last surveyed; this species may in fact still be in existence, if so, however, its future expectations are rather bleak.

Nuttall’s False Foxglove (Agalinis nuttallii)

This species is known exclusively from the type material which had been collected in 1819 on a river bank at the Arkansas River either in present day’s Arkansas or Oklahoma, USA.

The species has never been found again since and is believed to be extinct.
